Shut down your SMTP and you won't get any spam either. It's all about
the collateral damage we are talking here.

I don't really care about the number of spam messages received unless
they pass through my spamassassin filter which in turn uses SORBS and
other DNS blocking lists to achieve a pretty good hit rate.

Using a centralized SMTP relay host only makes things worse.

I can guarantee that no spam is being sent from my IP but I cannot do
the same for my ISP's SMTP cluster which serves a few million customers.
I cannot even reasonably blame my ISP if they inadvertently provide
access to a spammer or some careless customer who runs a SMTP relay.

The only ones gaining advantage from us using our ISP's SMTP relay host
are the famous three letter agencies making it easier or even possible
for them to monitor out outgoing e-mail.
